The article explores the evolving concept of security and defense, emphasizing recent EU initiatives that address a wide range of threats and aim to enhance national and European security through integrated and innovative approaches. The purpose of the study is to calculate and evaluate the defense capability levels of individual countries, explain them using the proposed approach, assess them within permissible limits, and compare various national economic sectors affecting the needs of the security and defense sector (SDS). The main research methods are empirical methods (analysis and synthesis), deduction, and graphic analysis. The article provides a schematic algorithm for assessing defense capability levels, introduces the use of a “need coefficient” for SDS calculations, and includes sector-specific data (using US indicators) on material and non-material values. It also suggests using an efficiency ratio to compare current and optimal defense capabilities. The level of defense capability of the countries was assessed according to the scales defined by the authors. Using a system of indicators, rather than a single complex indicator, provides a comprehensive view of defense sufficiency and allows for a detailed evaluation of its components. Thus, an approach is provided not only to determine the current and optimal levels of the country’s defense capability, but also to assess the nature of the influence of individual branches of the national economy on ensuring the defense and security needs of the state (by area)
